This invention is a collapsible rack for supporting a trough designed to be used in connection with juvenile tooth-brush drills and the like.

It is now common practice in the public schools to strongly emphasize the importance of dental hygiene, and tooth-brush drills have become a part of the daily school routine in many localities. However, the effectiveness of such drills is often impaired and proper instruction hampered, to say nothing of insanitary conditions being created, by the lack of proper and convenient facilities for catching and disposing of the saliva, water, etc/expelled from the mouths of the children during such drills. The eiiective disposal of this refuse is necessary and important not only for sanitary reasons, but also to prevent untidy conditions in the school room, or other quarters where the instruction is being given.

One of the objects of the invention is to provide a portable supporting rack of the character descrlbed, which may be placed in any desired position in a school room, so that the children may be conveniently assembled about it for the desired tooth-brush drills. A further object is to provide a stand of the character mentioned, constructed so that it into compact form, for convenient storage when not required.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings Figure 1 is a side elevation illustrating a rack constructed in accordance with the invention. Figure 2 is a top plan view of the rack with the trough removed. Figure 3 is an end view of one of the uprights. Figure 4 is a top view of one form of trough. Figure 5 is a similar view of a modified form of trough.

Referring to the drawing, a, 0;, represent two uprights, and b, b, and c, c, stayrods or braces by means of which the uprights are maintained in spaced relation, so that they will stand in upright positions These parts may be constructed of any deslred ma- Serial No. 249,615.

terial, but as shown in the drawing they are constructed of rodlike metal bent to the desired shape.

Referring particularly to Figure 2, it will be noted that each upright a is provided with legs 10, connected by a transverse bottom member 11, and side members 12. Said side members at their upper ends are bent downwardly as indicated at 13,. and horizontally as indicated at 14 to provide a trough support.

The brace rods are arranged in four sets two rods each. For instance, each rod 1; is provided at one end with a hook portion 15, shaped to removably engage a complemental portion 16 of an upright a, the other end of each of said rods 6 being provided with an eye 17. In a similar manner each rod 0 is provided with a hook portion 18, shaped to engage a complemental portion 19 of an upright a, the other end of each of said rods 0 being provided with an eye 20. As clearly shown in the drawings. The two rods 6, b, of each upright a converge laterally inward and are also inclined downwardly, so that the eyes 17 of both of said rods are brought into register with each other. In a similar way the rods 0 also converge laterally inward. and are inclined upwardly, so that the eyes 20 not only register with each other; but also with the eyes 17. A. rod or bolt 21 is rcmovaljily inserted through the registering eyes 17 and 20, so that the rods 1) and c are held against relative movement and the uprights a are firmly and rigidly held in vertical position.

It will thus be seen that the rods 6 and c are so arranged that two rods Z) and two rods 0 are each connected at one end to a frame a at relatively spaced points both vertically and laterally, and the other ends of said rods are brought together. The converged ends of both sets of rods are then detach'ably connected with each other.

The trough may be of any desired form, two examples being shown in the drawing. The form illustrated in Figure l consists of two sections 25, 25 having bevelled side walls and a flange 26. The contiguous portions of the flanges of adjacent sections are hinged together as indicated at 27, so that when the two sections are opened to the position illustrated in Figure 1, the adjacent portions of the flanges will abut and folding of the trough is prevented in suitable manner. Each trough is provided with a drain opening 28 which may be closed by a suitable plug.

In the form illustrated in Figure 5., the trough is shown as consisting of a single section 30. It is to be understood that the troughs may be made of any desired material,

but it is preferred to makethem of sheet .metal and to coat them with a bakedenamel,

or'other form of imperv ous coat ng wh ch will provide a hard, polished surface, capable of being easily cleansed and maintained in a sanitary condition. 7 V

The advantages of the invention will be readily apparent to those skilled in the art to whichit belongs, For. instance, it will be particularly noted that a very small and inern pensive. stand or. rack is provided, for rigid- 1y supporting a trough in a-position to perunit the convenient assembly of chndren around it for toothbrush drills. It will also be observed that the device is exceedingly sinn ple and inexpensive in construction, and by reason of the collapsible feature it may be readily knocked down and conveniently stored when not required, and yet may be quickly assembled and. placed in position on thelfloor of the school room whenever reforms in which it may be made, or all of the forms of its use,'what is claimed is 2- 1.
